hey i have a few questions. i used a dremel tool to mount this omnifi's headunit in the ashtray thingy, so i can flip the lid shut and hide it. but thats not the problem. i need to wire this sucker up now, and i need a dimmer wire, an only on with key wire, a always on wire and a ground, somewhere under the drivers side of the dash preferably. i dont think the dimmer is really a neccessity but the rest are. anyone have the colors for said wires? and general location? also, can you use low voltage tap-ins on this sort of application?
